FePOs nanozyme was prepared via a simple hydrothermal method.
In a typical process, H2NCONH2 (6.0 g) and sodium lauryl sulfate (SDS,
0.5 g) were dissolved in deionized water (84 mL) and then magnetically
stirred for 10 min to obtain a homogeneous solution. Afterwards,
Fe2(SO4)3 (0.2 g) and phosphoric acid (20% wt H3PO4, 0.490 g) were
separately dissolved in deionized water (8 mL), and then added dropwise
to the above solution, which was then magnetically stirred for
20 min. Next, the mixture was transferred into a 150-mL Teflon-lined
autoclave, sealed and maintained at 140 °C for 2 h, and then cooled to
room temperature naturally. The obtained product was collected by
centrifugation, washed with deionized water and ethanol, and finally
dried in a vacuum at 60 °C. |
